42 meters at the bottom of Chaohu Lake with a robot "Inspector"

On September 26, in the lake light road cable tunnel at the bottom of Chaohu Lake, Hefei City, the intelligent robot "inspector" had just completed a round of comprehensive inspection. , Upload the operation report to the Hefei Power Supply Company's high -pressure cable lean management and control platform.

Intelligent robots have 7 major functions such as environmental monitoring and emergency response

At the scene, along the orbit above the cable tunnel, the robot slowly drove automatically. Each pass through the middle connector of the key cable, it will stop and watch the high -pressure cables with "big eyes". Detection and analysis. "The operating temperature of these high -voltage cables is about 38 degrees, and the different temperature difference is within 2 degrees. The overall power supply is stable." Wang Mouchang, an employee of the cable transport inspection center of Hefei Power Supply Company.

It is understood that in 2020, due to the needs of the newly constructed Chaohu Bridge, the local government departments and Hefei Power Supply Company planned and built the 110 kV Lake Lake Lake Lake Lake Lake Tunnel, which relocated all the high -voltage lines above the lake. The overall Lake Guang Road Cable Tunnel is located 42 meters deep at the bottom of Chaohu Lake, with a total length of 780 meters. It was officially launched in December 2020. It is the first lake cable tunnel of Anhui Power Grid. It is also the longest and deepest professional cable tunnel in the province. Essence The inside of the tunnel is a collection of 110 kV West silver lines and nest flag lines. It is a veritable underground power supply "arteries". The importance is naturally self -evident.

Wang Mouchang said that before this inspection robot was put into operation, he and his colleagues needed to start from Hefei regularly and spent more than an hour to reach the bottom of the lake to test the high -pressure cables during operation. Carry out a comprehensive inspection of the internal environment, master the operation of the cable, and discover and eliminate the hidden dangers. "On September 9 this year, after 2 months of installation and debugging, this intelligent robot was officially launched. It has 7 major functions including video analysis, infrared temperature measurement, environmental monitoring, and emergency treatment. Hidden 'issues have strongly enhanced the level of intelligent transportation inspection of underground cables and alleviated the operation and maintenance intensity of our front -line employees. "Wang Mouchang said.

The hidden dangers of the robot discover problems, and send early warning information in time

It is understood that the staff sets the program in advance through the system, and this intelligent robot can inspect the high -pressure cable at the bottom of the lake every day. It has a visible high -definition camera internally, combined with a powerful video analysis algorithm, which can automatically identify the instrument data of the equipment in the tunnel and the existing appearance defects. The temperature measurement function can accurately grasp the operating temperature of the cable, accurately locate abnormal points and analyze and judge. Various environmental sensor equipment can be monitored in real time on environmental temperature, harmful gases, water accumulation, and personnel invasion.

Once the robot finds a hidden problem during the inspection, the early warning information will be sent to the high -voltage cable lean management platform at the State Grid Hefei Power Supply Company at 100 kilometers away. At the same time, the daily linkage of robots and high -voltage cable lean management platforms to analyze multi -dimensional analysis of each inspection data year -on -year and month -on -month, so that the staff can be more refined to grasp the running data trend of cable operation more refined Change, do a good job of targeted operation and maintenance, and further improve the reliability of power supply.

As of now, Hefei Power Supply Company is responsible for the operation and maintenance and maintenance of high -voltage cables in the city of 35 kV and about 489.5 kilometers of high -voltage cables in the city, accounting for 58%of the total high -voltage cable operation in the province. With the steady development of Hefei economic and society, the city's high -voltage cable scale has increased steadily at an average annual growth rate of 12%. At present, the company has initially established a "three -dimensional inspection+centralized monitoring" through a series of practices in the province's first establishment of a lean management and control platform in the province to complete the upgrade of the first smart cable tunnel upgrade in the Yuxi Road cable tunnel. The new mode of intelligent transportation inspection further improves the lean ability of Hefei grid cables and the reliability of urban power supply.
